: : The date in the header on the http://www.yutopian.com/history/qin.html: : page should be changed to 246 -- 206 BC. It was confusing before I: : realized it was a mistake!

: The reign of Emperor Shi was between 246 - 206 B.C. but the Qin Dynasty: lasted between 221 - 205 B.C. The Warring States (or Zhan Guo) did not: officially end until 221 B.C. when Qin Shi Huang unified China. While the : Qin Kingdom existed long before, the Qin Dynasty was marked by the unification : of China. The unification of China played a crucial role in the dating of the : dynasties by historians.

: Also, Qin Dynasty ended in 205 B.C., not 206 BC, because Emperor Shi's: son ruled for a short period after his father Shi died.
